Power Steering Pump Pulley Single V-Groove

The Power Steering Pump Pulley Single V-Groove (part number 8485B) from TUFF-STUFF is a precision-engineered replacement component designed for street rods, classic car restorations, and engine swap projects where compact serpentine belt systems are integrated. This single groove pulley serves as the driven component of your power steering pump, translating engine crankshaft rotation into hydraulic pressure for responsive steering control.

Manufactured by TUFF-STUFF—a trusted name in performance steering and suspension components—this power steering pump pulley features a single V-groove profile optimized for standard belt tension and load distribution. The design measures 6.85 inches in outer diameter and has a face width of 1.7 inches, allowing it to integrate seamlessly into tight engine bays and modern accessory drive configurations.

Weighing just 1.25 pounds, the pulley minimizes rotating mass, reducing parasitic drag on the engine while maintaining the structural rigidity required for continuous duty. The precision-machined grooved surface ensures positive belt engagement, preventing slippage during sharp steering inputs and maintaining constant hydraulic pump speed across the entire RPM band. Hot rodders, engine builders, and restoration specialists rely on this pulley for its reliable performance in high-demand automotive applications.
